Maximum Disk Shelves per Controller Configuration
When determining how many disk shelves a controller configuration supports, it is important
to remember that each disk shelf chain can support up to six disk shelves, and some controller
configurations are limited to a specific number of total disk shelves. The following table details
the number of supported disk shelf chains per HBA type.
TABLE 3
Supported Disk Shelf Chains per HBA
HBA Type Number of Disk Shelf Chains per HBA
SAS-3 4x4 port 2
SAS-2 4x4 port 2
SAS-2 2x4 port 1
Controllers cannot simultaneously use 2x4 port SAS-2 HBAs and 4x4 port SAS-2 HBAs. In
addition, only DE3-24 disk shelves can be connected to SAS-3 HBAs, and DE3-24 disk shelves
cannot be used in the same system as DE2-24 disk shelves or Sun Disk Shelves.
